FP-32C Flush Mounted On-Line Moisture Sensor

Reg. U.S. Pat. Off. No. 6,249,130 B1


  • Monitors particulate moisture content in physically hostile environments such as mixers, chutes, belt conveyors, and augers
  • A reliable, economical solution for many moisture monitoring problems

Product Specifications

The FP Series Flush Mounted On-Line Moisture Sensors are designed specifically for mechanically hostile environments and feature proven capacitive moisture sensing with a patented flat plate configuration. This allows sensing of granular materials in a mixer, an auger, or a chute.

Sensor output can be displayed on local display and/or transmitted as an analog signal for integration into a process control system. Temperature data are also readily available.
